Golang中没有&T类型,按照内置类型做分类,Golang里有int、float、string、map、slice、channel、struct、interface、func等数据类型,首先用int写一个和上文C++代码类似的例子: int 代码语言:javascript 代码运行次数:0 运行 AI代码解释 packagemainimport"fmt"funcmain(){a:=10086varb,c=&a,&a// b、c变量存的...

Another definition of systems programming is the stuff that runs in the cloud.--Rob Pike今天我探索了一下 golang 的两个方面:类似于 Java 中有很好的 Builder 模式 Getter 和 Setter 的命名约定然后我发现了函数选项(Functional Options)模式, GIST上有一个最小的例子。 函数选项模式是由Rob Pike提出,并...
